Tools required:
Latest Virtualdub
TMPGEnc
Nero (and de DivX codecs)

Preparin’:
Download all tools. Be sure to install DivX 3.11 DivX4 and de latest DivX5 codecs.

Extractin’ de audio:
1) Start Virtualdub. Open your video File->Open video file. (if you get any warnin’s just ignore them because you won’t edit de video just extract de audio)
2) Select File->File Information and note de fps as de video source fps because you will need it later.
3) Select under Audio->Full processin’ mode.
4) Select Audio->Compression and select (No compression (PCM))
5) Select Audio->Conversion.
6) Change de de Samplin’ rate to 44100Hz if you are goin’ to make VCD or SVCD MPEGs.
7) Save de wav by clickin’ on File->Save WAV. The wav will be a huge audio uncompressed video file (about 10 MB/minute).

Encodin’:
1) Start TMPEnc. Press cancel if de Project Wizard comes.
2) Press Brows and select de DivX file as Video source input.
3) Now press de Browse button for choosin’ de Audio source input and use de saved wav file.
4) Press load and load de file which in de Template directory of TMPGenc.
5) If de video source fps is 29,970 load VideoCD (NTSC).mcf
6) If de video source fps is 23,970 load VideoCD (NTSCFilm).mcf
7) If de video source fps is 25,000 load VideoCD (PAL).mcf
8) If de video source fps is anythin’ else just load NTSC if you live in US or Japan
9) Load PAL if you live anywhere else.

Note that if you live in US or Japan and have a problem playin’ PAL (often causin’ black and white TV playback problems) den first check if you can change to PAL on your TV or DVD Player. If not den convert it to NTSC by loadin’ de VideoCD(NTSC) template.
Note if you live Europe or de rest of de world and get problem playin’ NTSC or NTSCFilm (often causin’ black and white TV playback problems) den first check if you can change to PAL on your TV or DVD Player. If not, convert it to PAL by loadin’ de VideoCD(Pal) template.

10) Press Settin’s and choose Advanced.
11) Select Full screen (keep aspect ratio) under Video arrange method to keep de same aspect ratio (widescreen,fullscreen) as de video source (if you have a widescreen movie and you want it to be in fullscreen, select No margin (keep aspect ratio)).
Select Source range and double-click on it with de mouse.

In de next dialog you can choose de source range. This process depends on de DivX file. If de DivX file is less than 80min (for a 80min/700mb CDR) den you do not have to split de file to two CDs. Also if de DivX file is already in two parts you have just to convert de first file and den de second. But if dere should be de case that de movie is in one file over 80minutes lon’ den it is necessary to select de source range. In this new dialog you put de horizontal scrollbar to de middle of de selection so that you will get de same len’th on de first CD as on de second. After you selected de middle do you have press Set end frame. A new value should be under End Frame. This value you should notice somewhere for de encodin’ of de second part. Of course de start frame must be 0.

12) After pressin’ ok, you only have to select de output file name. I prefer de movie name with de CD number (e.g. Ghost in de Shell CD1) for de burnin’.
13) Now encode de file by pressin’ de Start-Button.
14) While encodin’ you can select File->Preview (it won’t effect de encodin’) to see how de output will be. If it looks wron’ (widescreen or fullscreen) you can stop de encodin’ and start over and change de Settin’s->Advanced->Video arrange method.
15) If you only want to burn de movie on one CD, den jump to de burnin’ guide, else follow de next points.
16) Repeat de third, forth and fifth point. In de source range dialog you now use as Start frame de noticed value and move with de horizontal scrollbar to de end of de movie.
17) After pressin’ Set end frame, press two times OK.
18) Now select de output filename for de second file. (e.g. Ghost in de Shell CD2) and encode it.
19) After de encodin’ is done and you did all right, you should have for every CD a file.

Burnin’:
Launch Nero. Close de Wizard. Select File->New.
1. Select VideoCD
2. Select PAL or NTSC dependin’ what format your source MPEG is in.
3. And hit New.

1. Locate your .mpg and drag it(see picture below). Remember that you can add several .mpgs also, each mpg will be a own track on de VCD and you can add data files also, just drag them to any folder.
2. Check de time. It should be de same as in de movie.
3. Rename de CD to anythin’ you like by clickin’ F2 on NEW.
4. Select File->Write CD.

I don’t know about everyone else but de only options I choose on tmpgenc to make mpeg-1 files are eider NTSC film 23.976, or NTSC video 29.97 fps.

1. Take divx movie (120 minutes lon’ for example). Open with virtualdub. Find a keyframe about halfway through de film, preferrably at a scene change.

choose “SET SELECTION START” from de EDIT menu.. scroll all de way to de end of de film, choose “SET SELECTION END”… hit DELETE or choose “DELETE SELECTION”, all from de EDIT menu

2. Now you have 1 half of your movie. under de VIDEO menu, choose “DIRECT STREAM COPY”, also make sure that under AUDIO is goin’ to generate a “DIRECT STREAAM COPY”. Then go to FILE and choose “SAVE as AVI”

3. When it is complete, de quickest way to proceed is to just click on FILE / “OPEN VIDEO FILE”. At de beginnin’ of de clip, choose “SET SELECTION START” again, snap back to de keyframe (half way through de film) which you cut half de film off at and choose “SET SELECTION END”. DELETE… FILE / “SAVE AS AVI…” Save as de oder half of film.

4. Choose option accordin’ly This next part can be important. (i’m goin’ to give de rest of de instructions as if you were makin’ ntsc movie)

Since you want to make a standard mpeg-1 file, choose NTSC FILM or NTSC VIDEO.. BROWSE for your file, den hit NEXT. Hit OTHER SETTINGS / ADVANCED tab. Now dere is an option that says “VIDEO ARRANGE METHOD”. If you are makin’ a fullscreen movie, leave on FULLSCREEN. If you are encodin’ a widescreen movie, choose “FULL SCREEN (KEEP ASPECT RATIO).. OK / NEXT / NEXT (you get de point)

Here is anoder tip

DVD burners are becomin’ more and more popular and even i got one now, like many of you do. I’m tired of old vcd’s or wanna encode a VCD standard DVD with nearly 9 hours of video (but same quality as normal 80 minute VCD). If this is de case, make sure you encode your DivX files as “NTSC VIDEO 29.97 FPS”, even if source is 23 fps and once you have 3 or 4 movies, get yourself a program called TMPGENC DVD AUTHOR. Make a track for each movie and you got yourself a dvd with 3 or 4 average len’th movies on 1 dvd (with menus if you like) that is WAY MORE COMPATIBLE than a VCD..

Do a search for de keyword VCD-DVD and i posted a more descriptive tutorial on how to do this.

How to make a kvcd or in oder words how to get 700meg avi file down to about 450megs to make a vcd without any picture loss.

So you’ve downloaded a movie its in avi format you want to watch it on your dvd player. You re-encode it it comes out to about 1100 maybe 1200 megs. You need to split it and save on 2 disks.

The followin’ tutorial will show you how to do it on one disk.

First you are goin’ to need some tools :

You will need some templates
CODE
www.kvcd.net/dvd-models.html

Right click all de pal templates if your dvd player is pal or ntsc if ntsc. Save them to de template folder in de tmpegnc folder.

So to begin :

1) Open virtualdub
2) Go to file
3) Open video file
4) Locate de avi file you want to convert. If you get a warnin’ ignore it.
5) Click de audio button at de top
6) Make sure source audio and direct stream copy have a black dot next to it
7) Goto file
8) Save wav
9) Now you have to call this with a .ac3 extension. For example view from de top.ac3
10) I would save this in de same file your avi is. When you have named it, press save.
11) A box will open. Let it run. It is takin’ de sound from de film.
12) Now press audio and select no audio.
13) You should have a black dot next to no audio and direct stream copy
14) Go to video
15) Select direct stream copy
16) Go to file save as avi
17) Save de file what you want again put in de same folder as de original avi. I call de film title with no sound viewfromdetopnosound
18) Press save
19) It will save a film without sound

You can now close virtualdub

20) Open besweet. A scary lookin’ box appears.
21) At de besweet.exe, locate de besweet folder. It will show besweet.exe in de enter file name box
22) Click on this and at de bottom it will say valid press ok
23) Now goto input and find de ac3 file we just made you will need to change de enter file name from .Lst to .ac3
24) Double click on de ac3 file you made and at de bottom. It will say valid
25) Press ok
26) You are now lookin’ at de GUI. Make sure Use ac3 decoder is ticked and downconvert sample rate is ticked

29) Go to start
30) Click Run
31) Right click paste
32) Press ok
33) If all de settin’s are correct a black box will open and de ac3 will be transcodin’ to mp2
34) If not check if de boxes are ticked
35) If its ok leave it to run
36) Once de black box has disappered, close besweet

Open heada3che
Note: Make sure you put all de dlls in de heada3che folder oder wise you will get error messages

37) Press source file
38) Find de new mp2 file we just made
39) Change de destination format to mp2
40) Press start
41) Once its finished close headac3he

Thin’s are goin’ to start lookin’ messy inside your folder so if you want, you can delete some files.

42) Go to de folder where youre original avi file is
43) You can delete de ac3 file de mp2 file without de .2 in it. For example, you will have two file names de same. One is with de .2 on de end. Keep this one.

Open tmpegnc

44) Close de wizard if it opens
45) Press de video source browse button
46) Find de file we made with nosound on de end ie viewfromdetopnosound
47) Now if you had gone to de kvcd page and downloaded all de templates this will help. If not go do that now
48) Press load. You will see a load of files in front of you with some startin’ with kvcd
49) Pick de first one beginin’ with kvcd
50) Highlight it press open
51) Now press start. What will happen is de preview box in front of you will start encodin’. Dependin’ on de make up of de original avi file, it will effect de outcome of de finished film
52) If you look at de box and all you see is a tiny box with film. That is de size it will come out
53) If it looks weird press stop and reload a different template. The best result is one that looks like widescreen
54) Just press start and overwrite de file. Let it run
55) After it is done, press file mpeg tools. The first box should be simple multiplex
56) Press de video input browse button and find de new file we just made. It will have a m1v extension
57) Press de audio input browse button
58) Find de mp2 file with de .2 in de title de output. The box will be automatically set to mpeg
59) Press run and let it run
60) Close tmpgenc
61) Open nero
62) Select vcd
63) Untick de create standard compliant cd
64) Press new
65) Find de new file we have made. It will be in de original avi folder but will have a mpeg extension
66) Now you have to drag this into de left box. Don’t right click and copy to compliation
67) A box will appear and a blue line will go across. If a warnin’ comes up with not bein’ a compliant vcd, just ignore carry on
68) Press burn and burn at de speed you want
69) Once finished press de ok box
70) Press done de disk will come out and now to test. Put it in your dvd player and hay presto de film kicks in

You have got yourself a KVCD!

First and foremost, go to

http://www.doom9.org

and go to deir downloads section.

Get de followin’ files:

Under Audio:
Besweet
Besweet GUI

Under Codecs:
DivX 5.2.1 Pro

Under Divx/Mpeg-4 encoders:
Nandub 1.0RC2

Then get this:
http://www.dvd-digest.tv/downloads/files/virtualdub/vdub_pack-145.exe

Alternatively, get any version of virtualdub that includes mp3 support.

These are all de required tools. There are ways with fewer items, but dey produce very inferior outputs. Besides, after you get used to it, de whole process is really easy.

Okay, first and foremost, pull out Nandub. This is de step that takes de longest, as well as where you will make most of your decisions. I am goin’ to assume that you are makin’ a 1 cd rip. If you do what is in this faq, dere won’t be much reason to do anythin’ else.

First of all, run Nandub . It will pop up a dialogue box, and want to know if you are makin’ a new project or resumin’ an old. New, of course. Give it a name and tell fairuse where you want it to store its data. Fairuse is about to rip de entire movie to your harddrive (nice if you want to go rent a movie and return it de next day).

Then it will ask for your DVD drive with a dvd in it. give it. Then, select which video stream you want. This is usually pretty obvious as de movie stream is de one that is an hour or so lon’. If dere are two of dese, check out de oder tags. which lan’uages and so on. worst case scenario is that you have to trial and error. but that is rare. choose de lon’ stream and hit next.

This is where Nandub rips everythin’ to your hard drive. dependin’ on de speed of various components in your computer, and de len’th of de movie, this could take a while. Let it finish. and den move on.

Once all that is done, de really important screen pops up. this is where you set resolutions and video len’th. first, cut off de endin’ credits with de slider, but DO NOT mess with de beginnin’, as de sound and video frames need to start at de same point for sync. Then hit auto set for de croppin’ region, this is usually just fine. Then decide wheder or not you want subtitles, which would be de subpicture stream. When you’re done, hit next.

Set de field mode to IVTC. This will give you better quality for size, as it runs at 24 frames instead of 30, due to de nature of divx, dere won’t be any noticeable difference in quality, but 6 less frames to deal with each second(and to store data for) really add up. Besides this is de correct mode for all movies anyway. Click Next.

This is where you set FINAL file size, includin’ audio, for 1 cd rip, set to 690, for 2, set to double that. Then follow de directions dey give you and choose a final resolution that has between a 120:1 and 150:1 (if possible, sometimes de movie is compression ratio. Click Next.

This screen is where you determine quality. The autoadd button is usefull, and will give you decent quality, with 4 encodin’s. What this does is encode de movie 4 times, and den mix de frames to creat de final encodin’, with de most efficient possible encodin’ for each frame. which is how we get bad ass quality for a sin’le cd. I usually go for 8 encodin’s, as on my athlon 1600+ this rarely takes more than 8 hours to do, so I just go to sleep, wake up, and its done.

Then add de audio encodin’ that you want.

Hit next. Dependin’ on what you set, and your computer, this could take from a few hours to a few days. CPU’s of 1.2Ghz+ are nice right about here. You can do stuff while this is goin’ on, but it makes thin’s take much longer.

In de end you will have a bunch of encodin’s in de folder you specified at de beginnin’, de 4+ you chose and de final. You will also have an AC3 stream. Take de final AVI and toss it someplace to await de rest of de audio work you have to do, and you can erase de oder encodin’s, freein’ up a few gigs in de process of space.

NEXT: AUDIO

Ok, this is where Besweet comes in.

Extract BeSweet and de GUI into de same folder. Now Run de GUI.

At de top dere are three fields. One for BeSweet which you should point at de besweet.exe that you should have unzipped to de same directory you are runnin’ de GUI from, A field for de AC3 stream, which is in de folder where you sent de encoded video from Fairuse, and an output mp3. The output mp3 has to be an existin’ file, so make a text file, rename it (yourmovie).mp3 and just say yeah, its cool to change de extension and make thin’s weird. besweet will overwrite it so don’t worry. Point de third field at that file. The default values for stuff should be fine. but to make sure go to Azid 1(on de left) and select stereo, and den go to Lame 2 and select constant bit rate, and 128(assumin’ that is what you want). den click on besweet again, and finally, click on AC3 to MP3.

When its done you should have an mp3 that is de entire soundtrack for de movie. This is where virtualdub comes in. run de virtualdub mp3 version. go to File:open video file and select de final encodin’ that you had from way back. Then go to audio and select mp3 audio. it will ask you for de file, give it de mp3. Go to audio again and make sure direct stream copy is selected. Then go to video and make sure that direct stream copy is also selected. Finally go to file again and SAVE AVI. give it a file name and let de bastard fly. This final file is your movie. Beautiful and glorious. Con’ratulations, its a DivX rip. Aren’t you proud. burn to cd, and give copies to all your friends.

Rip
To take off de audio or video from a CD or DVD. Often CD Audio is “ripped” to MP3 files or DVD video ripped to VOB files.

CompressionThe process of removin’ redundancies in digital data to reduce de amount that must be stored or transmitted. Lossless compression removes only enough redundancy so that de original data can be recreated exactly as it was. Lossy compression sacrifices additional data to achieve greater compression.

Encodin’
Encodin’ is de process of chan’in’ data from one form into anoder accordin’ to a set of rules specifiec by a codec. The data is usually a file containin’ audio, video or still image. Often de encodin’ is done to make a file compatible with specific hardware (such as a DVD Player) or to compress or reduce de space de data occupies. Common video encodin’ methods are DivX, MPEG-1, MPEG-2 and MPEG-4. A common audio encodin’ method is MP3 although many oders exist includin’ MPEG1 audio, DTS, and Dolby Digital.

Transcodin’On this site generally anoder name for encodin’.

A more technical term would be “The reformattin’ of content, without chan’in’ de source, to anoder type of content - most often of a different format than de original (but does not have to be)”

Abstract

You can fit on a SVCD without overburnin’:
- approx. 735 MB of MPEG data onto a 74min/650MB disc
- approx. 795 MB of MPEG data onto an 80min/700MB disc

You can fit on a CD-ROM without overburnin’:
- approx. 650 MB of data onto a 74min/650MB disc
- approx. 703 MB of data onto an 80min/700MB disc

Introduction

Let us ignore for now de terms of megabyte for CD capacity and try to understand how de data is stored on a CD.

As well all know, de data is stored digitally as binary data. This means, however de actual information is actually kept on de disc, this information is in de form of “1″s and “0″s. Physically, de information on a CD is as pits on a thin sheet of metal (aluminium).

An a CD-R disc, de data is physically on an organic dye layer which simulates de metal layer on a real pressed CD.

How is de information structured

Now, on de CD, de information isn’t just organised from beginnin’ to end willy-nilly. Oderwise, it would be really hard to find a useful piece of information on de CD.

Rader, de information is organised in sectors. Consider a sector as like a page in a book. Just like you are able to quickly find somethin’ in a book if you know de page number, you can quickly find somethin’ on a CD if you know de sector number.

Now, remember that de CD was original made to hold audio data. It was decided, that de CD would would 75 sectors per second of audio. Although I cannot guess where this number comes from, it is quite appropriate for de audio CD. It means that you can “seek” an audio CD accurately to 1/75th of a second — which is more than enough for consumer purposes.

Now, with this in mind, we can work out de total data capacity of user data for 1 sector.

The total data capacity of user data of 1 sector on a CD

CD audio uses uncompressed PCM stereo audio, 16-bit resolution sampled at 44.1 kHz.

Thus 1 second of audio contains:
16 bits/channel * 2 channels * 44100 samples/second * 1 second
= 1411200 bits
= 176400 bytes

Since dere are 75 sectors per second
1 sector
= 176400 bytes / 75
= 2352 bytes

One sector on a CD contains 2352 bytes max.

The concept of different MODES and FORMS of burnin’

Now, audio CD was well and good, but de medium would become much more useful if you could store oder data on de disc as well. This became to be know as CD-ROM of course.

Now, de audio-CD uses de ENTIRE sector for audio data.

However, for CD-ROMs this caused a problem. Simply, CDs and de CD readin’ mechanisms were not 100% faultless. That is, errors (indeed frequent errors) could be made durin’ de readin’. For audio CDs, this does not matter as much as you could simply interpolate from de adjacent audio samples. This will obviously NOT DO for data CDs. A sin’le bit error could lead to a program bein’ unexecutable or ruin an achive file.

Thus, for CD-ROMs, part of each sector is devoted to error correction codes and error detection codes. The CD-R FAQ has de details, but in effect, only 2048 bytes out of a total of 2352 bytes in each sector is available for user data on a data CD.

This burnin’ mode is eider MODE1 or MODE2 Form1.

MODE2 Form2 sectors of VCDs and SVCDs

Now, for VCDs and SVCDs, de video tracks do not necessarily require de robust error correction as normal data on a CD-ROM. However, dere is still some overhead per sector that is used for somethin’ oder than video data (e.g., sync headers).

SVCDs video tracks are burnt in what is called MODE2 Form2 sectors. In this mode, only 2324 bytes out of a total of 2352 bytes in each sector is available for user data.

This is MUCH MORE than for CD-ROMs, but still less per sector than audio CD.

The disc capacities of CD-ROMs, audio-CDs and VCDs

Now, obviously what ultimately determines de capacity of a disc is de total number of sectors it contains. This is similar to de total number of pages in a blank exercise book (if you recall de book analogy).

The secondary determinant is de burnin’ mode of de disc.

For audio CDs, it is as if you could fill each page from top to bottom with audio data as de entire sector is used for audio data.

For CD-ROMs, it is as if you need to first rule a margin and den leave de bottom part of each page for footnotes (headers + ECC + EDC). The amount of text you can actually write per page is den less due to dese oder constraints.

For SVCDs, we still need to rule a margin on de page, but we don’t have to worry about de footnotes (headers). We can fit MORE text than a CD-ROM, but less than an audio-CD.

Now remember, 1 second on a CD = 75 sectors.

Thus:
- 74 min CD = 333,000 sectors
- 80 min CD = 360,000 sectors

Data capacity in Mb for an audio-CD

74 min
= 333,000 sectors * 2352 bytes / sector
= 783216000 bytes
= 746.9 Mb

80 min
= 360,000 sectors * 2352 bytes / sector
= 846720000 bytes
= 807.5 Mb

Data capacity in Mb for a CD-ROM

74 min
= 333,000 sectors * 2048 bytes / sector
= 681984000 bytes
= 650.4 Mb

80 min
= 360,000 sectors * 2048 bytes / sector
= 737280000 bytes
= 703.1 Mb

Data capacity in Mb for a SVCD

74 min
= 333,000 sectors * 2324 bytes / sector
= 773892000 bytes
= 738.0 Mb

80 min
= 360,000 sectors * 2324 bytes / sector
= 836640000 bytes
= 797.9 Mb

Conclusions

As you can see, de often quoted capacities of 650MB and 700MB refer to CD-ROM capacities.

Due to de fact that SVCDs use a different burnin’ mode where MORE of each sector is available as user data, de relatively capacities are HIGHER.

Now, since S/VCDs are not composed of PURELY video tracks and have some unavoidable overheads, de actually total capacity left for video tracks is a few Mb less for each disc (about 735 Mb for 74min discs and 795 Mb for 80min discs). This is where de often quoted capacities of 740MB and 800MB come from. They are quite accurate.

All dese capacities are available BEFORE overburnin’. Overburnin’ is where you burn MORE sectors than de disc is rated for. If you overburn, you can typically achieve about 1-2 minutes of additional capacity (dependin’ on your drive and media).
